I recommend pressing the Reset button, as per the manual's instructions "perform factory reset."

Are you trying to avoid logging into the webpage of each camera, as a user, and using the web page to configure more users and groups? (I don't know the answer to your question.) I looked briefly at the API doc and there's no way to add or delete groups.

Best practice would be to disconnect the RJ45 male (network cable) from the RJ45 female (camera harness) using the tab on the male RJ45 connector. This is preferable to cutting the camera harness, at least where I'm from.

WDR also disappears when the camera is set to 60Hz indoor/outdoor flicker prevention.

I think Smart IR setting tells the camera to run a control loop where it adjusts the brightness of the IR emitters based on how much light is in the scene.

The connections on the RJ45 connectors and cabling from your network switch to your port that the camera connects to are industry standard, nothing to do with Dahua.

Setting i-frame rate to 1 per second is not optimal. It is inefficient and results in larger bitrate than is necessary.

I find WDR-25 to be the best general setting. SSA can look nice and show lots of brightness in the shadows, but it is almost too much. And most importantly, I end up with SSA cameras often doing a 'hunt' or fresh brightness calibration every so often, say once every 30 minutes: they go full...

Not that I can prove it, but I'm pretty sure that, given a scenario of finite storage space per camera (let's say 10GB / day) of continuous recording (aka 24/7), then VBR will result in overall better footage to look back at than CBR - both during the boring times and the interesting times...

It can be entertaining to upgrade firmware every year. But usually there are no problems that need fixing, and sometimes the upgrade will modify some functionality you care about. The more advanced and special features you use (such as motion tracking, object tracking) the higher the risk a...

Interesting point. I recall seeing times in XProtect Expert where I've added a device that exceeds the license, and it adds to the system but then doesn't go online state - it has the 'offline' state icon beside it, and with the mouseover tooltip it says something like 'license exceeded'. With...

Yes, 1 device license per channel of the NVR. This is a relatively new policy of Xprotect, I would estimate about 2 years ago. Prior to that, devices like an NVR with multiple cameras inside would only consume one total device license.

A few thoughts: You didn't specify a version of XProtect, so no way to answer with specifics You didn't specify how many cameras are being watched simultaneously per computer, and what these cameras' resolution, framerate, bitrate, and encoding codec are Milestone certified partners have access...

I'm running a Xprotect expert 2022r2 system with the Dahua X72A3A4 NVR version V4.001.0000000.15, Build Date: 2021-10-13 . Xprotect is set to connect via ONVIF Conformant Device, admin account. When I look in the NVR's config pages for users, I see an admin account in both Account and in ONVIF...

What if you were to add a second NVR? Connect it to the same cameras in parallel (if analog camera cables). Then each NVR has its own IP, physical network connection, and credentials.
